Write a short paragraph to answer these questions and write word equations for the neutralisation reactions that happen.
What are the acids present in soils?
What is the name of the base used to neutralise soils?
What would the salts be called that are produced in this reaction?
What other products would be produced?
Soils contain a variety of acids, including carbonic acid, nitric acid, and sulfuric acid. The base used to neutralise soils is usually calcium hydroxide, also known as slaked lime. The salts produced in this reaction are calcium carbonate, calcium nitrate, and calcium sulfate. Other products produced in this reaction are water and heat. The word equations for the neutralisation reactions are:
Carbonic acid + Calcium hydroxide → Calcium carbonate + Water
Nitric acid + Calcium hydroxide → Calcium nitrate + Water
Sulfuric acid + Calcium hydroxide → Calcium sulfate + Water
